Stitching

Note

  • You can only stitch one system at a time.

  • AMBA Designer does not support stitching third-party IP-XACT components.

  • AMBA Designer stitches systems that comply with IP-XACT. In particular, bus interface connections must be wired point-to-point connections and no bus interface fanout is supported. For example, on the NIC-301 AMBA Interconnect APB master interfaces, AMBA Designer extracts each individual APB slave slot so that you can stitch each of these slots individually.

  1. In the main menu, select Design → IP-XACT RTL Stitching....

    AMBA Designer displays the AMBA Designer - RTL Design Flow Manager dialog box.

  2. Click Preferences to open the Stitcher Preferences dialog box. For information on the stitching settings, see Stitching parameters.

    Make the necessary changes and click OK.

    Note

    • If the Auto Add Stitched System to Component Library flag is selected in the IP-XACT Stitching tab, the system is automatically added to the Component Library when you close the dialog box. Otherwise, no action is taken.

    • To bring all the unconnected signal ports in the system up to the top-level, select Export all unconnected in the AMBA Designer - RTL Design Flow Manager Preferences dialog box.

  3. In the AMBA Designer RTL Design Flow Manager dialog box, click Stitch RTL to start the process.

  4. Click Close to close the AMBA Designer - RTL Design Flow Manager dialog box.

If the Auto Add Stitched System to Component Library flag was set in the Preferences dialog, the new component representing the stitched system is added to the Component Library. It appears in the Component Window with a system icon and the name you gave it when you saved it. Figure 18 shows the example system saved as NIC_301_PL340.

IP stitching generates reports in the following directory during the stitching process:

/home/<user>/.ARM/AMBA_Designer/3.0/Designs/<SysName>_RTL/

The reports depend on the components that you include in your design.
